What is over 9000 anyway?

Answer 1

The popular phrase "Over 9000" originated from the anime, Dragonball Z. Nowadays, people say it to describe something of great magnitude and power or simply for fun. In the anime, the antagonists, Vegeta and Nappa, are facing against the show's main protagonist, Goku, and they are surprised by his power level. In the show, the characters use a device called a scouter that measures a person's power level.

Before they fight, Nappa asks Vegeta what his scouter says about Goku's power level. Vegeta responds, "It's over 9000!" and he crushes his scouter in doing so since he has never witnessed such an enormous power level before.
